Breakdown Generator

A breakdown is a sparse, heavy passage in metalcore and deathcore where the tempo feels halved and the riff is built from short, muted hits on the lowest strings. The silence between the hits matters as much as the notes, and the crowd waits for it.

Typical ingredients are a low tuning such as Drop C or Drop B, palm mutes, half-time drums with the snare on beat three instead of beats two and four, and a last note that rings out. The generator follows exactly that model.

The riff sits on the lowest string and on the root note of the chosen tuning, in natural minor. The rhythm is picked from ten handwritten patterns of sixteen sixteenth notes each. A hit is an x and a rest is a hyphen.

With four bars, the first pattern plays three times and a second pattern closes the last bar, so the riff repeats and then answers. With two bars, each pattern plays once. The first hit of every bar is an open string and is accented. The other hits are mostly open string, with an occasional fret 1, 3 or 5.

The tempo can be set between 50 and 140 BPM and defaults to 75. The same seed, tuning and tempo always give the same riff.

A breakdown sounds heavy when the hits land exactly on the beat and the muted notes are dry. Precision does the work, not speed.

• Rest the side of your picking hand lightly on the strings near the bridge for palm muting. Too much pressure gives dead notes, too little leaves strings ringing.
• Count the sixteenth notes out loud: one, e, and, a. Make every rest as long as it is written.
• Start at 60 BPM and raise the tempo only when every hit is clean. Use downstrokes for an even attack.
• Let the last note ring without muting, as the generator does. Make a clear ending before the next section.
• Play along with the drums in the tool to feel where the snare lands.
